ARRANGEMENT FOR COOLING AND HEATING BEDS Filed April :5, 1930 PM Au 1931 PATENT OFFICE ALBERT UIH'IIIG, OF BOBSCHACH, SWITZERLAND (mum-ii rcncoonme AND EEATDTG :enns

Application filed April 3, 198 0, Serizil No. 441,382, and in Switzerland June 2-, 1929.

it is to heat in ser.

enerelly hoiwn, that his desirous beds inwinter and to cool the same beds in the winter heat only certainportions and their use is connected with dangers such es explosions of water bottles and infiagrations when heating cushions are used.

This invention reietes to an arrangement for cooling and heeting beds, by which certein inconveniences connected with the hitheiiO used epperotus have to be obviated,

is attained by e pipe system in which bioeer, en electzic heating body and e cooling body ere mounted, seid bodies edept-' ed to be switched in or out out es desired,

the pipe system communicating with the distribuiing eieinents mounted in the bed.

An embodiment of *heinvention is illustreted by We oi example in the only figure oi the accompanying drawing, showing diegrenimnticeily o, bed in side elevation and e bed top plen View and further the pipe system end eccessories,

A blower l, preierebiy driven from on 'electroniotor, hes e succion pipe 2 communi- With the atmosphere and eoressure 35 cermineting in n flanged transverse pipe at. Atthe one end oi t e transverse heating pipe 5 is fixed, e register 6 being inserted between 4.2 end 5, To the other end of tnensverse pipe i a cooling pigs 7 isconnected, e register 8 being ineresd between 4: end '2, The heating pipe 5 end the cooiing nine '3' end both in scone Icon oipe 9, from which branch pipes 10 lead to the beds,

At the foot end oi. ench bed a distributing pips is ernenged, fined on ihe end of the corresponding branch pipe 10 and situated. the space 12 between the sheet and the oisnhet. if n person is iying' in thebed specs 11.2 is suificiently Wide to permit nree passage of thesuppiied eir.

iin the heating pipe heating bodies 17 are mounted, "so which curreni, is supplied from c. senses of current 15, a switch 16 being inserted in the circuit. 'When the heating bodies are switched in, the air in the heating pine is heated In the cooling pipe 7 a serpentine pipe 19 is inserted, which is located in e. reirigerab ing box 18, having a filling 12 of ice and The commonly used devices for heating The distributing pipe 13 might be mounted in a hollow space in the mattress, in which case the distributing pipe s a serpentinepipe; or several straight pipes may extend along the foot and the sides of the bed.

The air biown into the may be disinfooted or perfumes may be admixed with the some. in the pipe 9 e filter 21 is mounted which may be disinfected Oi rendered odorous by means of the air flowine through. The pipes 5, 7, 9 end are preferably covered with insuieting material, so that loss of heat or cold is nvoided.

The driving motor for the biower is preferebly electrically connected with the circuit of the electric heating bodies so that these heating bodies cannot be switched in 'Without simultaneous switching in of the biower,

' The installation or arrangement described end shown is suitable for domestic use or for hospitals, as any desired number of branch pipes 10 can be branched from the common pipe 9.

For patients as Well as for pec ale of good heeith is useful end agreeable to here the bed heated or cooled as required.

1. An srrengenient for heating or cooling beds, comprising in combination e blower, a heating pine connected with said blower, e cooling pipe connected "with said blower, a common pipe to which said heating pipe and said cooling pipe are connected, electric beeting bodies in said heating pipe, e refrigerctor interposed in said cooling pipe, branch pipes one for each bed branching from said common pipe, a. distributing pipe at the end of each branchg'pe situated in the foot end of each bed an means for selectively connectin with said blower said heating pipe or sai cooling pipe.

'2; An arrangement as specified in claim 1, 5 comprising in combination with the pressure pipe of the blower the heating pipe and the J cooling pipe, registers one between said heating pipe and said blower and the other one between said cooling pipe and said blower. 3. An arrangement as specified in claim 1, comprising in combination with the cooling pipe, a refrigerator box filled with icev and salt, and a serpentine pipe in said box, terminating at both ends in said cooling p pe.

4. An arrangement as specified in claim 1,. comprising in combination with the common pipe, a filter in said common pipe designe to contain disinfecting substances or perfuming substances,

In testimony whereof I afix my si ature.
